Life Cycle of Rats and how to control it

The life cycle of rats consists of several stages, beginning with birth after a gestation period of about 21-23 days. Newborn rats are hairless and blind, relying on their mother for warmth and nutrition. Within 2 to 3 weeks, they begin to grow fur and open their eyes. By the time they are five weeks old, rats reach sexual maturity and can start reproducing.

A single female rat can produce up to 6 litters per year, with each litter containing 5-12 pups. This rapid reproductive cycle means a single pair of rats can exponentially increase their population in a short time.

Under optimal conditions, a pair of rats and their offspring could result in over 1,500 rats in just one year.

The average lifespan of a rat in the wild is about one year, but in protected environments, they can live up to three years. This high reproduction rate and relatively short maturation period contribute to their potential for rapid population growth and the need for effective pest control measures​ (​.

Signs of Rat Infestation

Learn how to recognise rat infestation compared from other pest infestation


Rat droppings are small, dark, and pellet-shaped. They are commonly found near food sources, along baseboards, in cupboards, and under sinks. Fresh droppings are shiny and dark, indicating recent activity, while older droppings are dull and crumbly.

Gnaw Marks

  • Rats gnaw on a variety of materials including wires, wood, plastic, and even concrete. Commonly affected areas are electrical wiring, wooden structures, and stored goods. Rat gnaw marks are larger and rougher compared to the finer marks left by mice. Look for irregular, rough edges.

Tracks and Runways

Rats and Mice leave greasy smudge marks from their fur and footprints along their regular paths. These tracks are often found along walls, beams, and in dusty areas.

Inspect baseboards, attic beams, and other undisturbed areas where rats might travel frequently.

Nesting Materials

Rats use shredded paper, fabric, insulation, and other soft materials to build their nests.Nests are commonly found in hidden, dark areas such as attics, wall cavities, basements, and under appliances.


Rat activity is most audible during the night when they are most active. Typical noises include scratching, scurrying, and squeaking sounds, often coming from walls, ceilings, and hidden areas.


Rat infestations produce a strong, musky odor, often described as a stale urine smell. Rat odours are more pungent and persistent compared to other common household odours like mold or garbage.

HOW TO SPOT A RAT INFESTATION - Rat Control in Singapore

Health Risks Associated with Rats


  • Leptospirosis is a bacterial infection that spreads through contact with water or soil contaminated by the urine of infected rats. It can also be contracted by direct contact with rat urine or tissues, the typical case is an infection from urine on a soda can and that’s why rat control in Singapore is a must-have.
  • Symptoms and health impacts: Symptoms of leptospirosis include high fever, headache, chills, muscle aches, vomiting, jaundice (yellow skin and eyes), red eyes, abdominal pain, diarrhea, and rash. In severe cases, it can lead to kidney damage, liver failure, meningitis, or respiratory distress.
  • Prevention tips: To prevent leptospirosis, avoid contact with water or soil that may be contaminated with rat urine. Wear protective clothing and gloves when handling potentially contaminated materials. At home ensure proper sanitation and hygiene, seal any entry points to prevent rats from entering your home, and eliminate sources of standing water where rats can leave their urine.


  • How rats spread salmonella: Rats can spread salmonella bacteria through their feces, contaminating food and water sources. The bacteria can also be transferred indirectly when rats walk on surfaces or through contact with contaminated objects.
  • Symptoms and treatment: Symptoms of salmonella infection include diarrhea, fever, abdominal cramps, and vomiting, usually occurring 6 hours to 6 days after infection. Most cases resolve without specific treatment, but severe cases may require antibiotics and hydration therapy.
  • Prevention measures: To prevent salmonella infection, maintain good hygiene by washing hands thoroughly after handling food or coming into contact with potential rat-contaminated areas. Store food in sealed containers and keep kitchen surfaces clean. Implement effective rodent control measures to reduce the risk of contamination.


  • Airborne transmission from droppings and urine: Hantavirus is primarily transmitted through the inhalation of dust particles contaminated with rat droppings, urine, or saliva. This often occurs when cleaning or disturbing areas where rats have been active.
  • Symptoms and health effects: Early symptoms of hantavirus infection include fever, fatigue, and muscle aches, particularly in the thighs, hips, back, and sometimes shoulders. These symptoms can be followed by headaches, dizziness, chills, and abdominal issues such as nausea, vomiting, diarrhea, and abdominal pain. Severe cases can progress to hantavirus pulmonary syndrome (HPS), characterized by coughing and shortness of breath, which can be life-threatening.
  • Safety precautions: To prevent hantavirus exposure, avoid sweeping or vacuuming areas with rat droppings and urine. Instead, use wet cleaning methods with disinfectant to reduce dust. Wear gloves, masks, and protective clothing when cleaning infested areas. Ensure proper ventilation and seal any entry points to prevent rats from entering your home.

Rat-bite Fever

  • Transmission through bites or scratches: Rat-bite fever is transmitted through bites or scratches from infected rats, as well as through contact with rat urine or mucous secretions. It can also be contracted by handling rats or consuming food or water contaminated with rat feces.
  • Symptoms and potential complications: Symptoms of rat-bite fever typically appear 3-10 days after exposure and include fever, vomiting, headache, muscle pain, joint pain, and a rash. If left untreated, rat-bite fever can lead to severe complications such as endocarditis (inflammation of the heart lining), meningitis (inflammation of the membranes covering the brain and spinal cord), and pneumonia.
  • Prevention and treatment: To prevent rat-bite fever, avoid handling rats, and take precautions if you must handle them by wearing gloves and protective clothing. Clean and disinfect any bites or scratches immediately and seek medical attention. Rat-bite fever is treatable with antibiotics, so early diagnosis and treatment are crucial. Implementing effective rodent control measures can also help reduce the risk of exposure.

Preventing Rat Infestations

Prevention Strategies for Homes

Rat Prevention Strategy infographic, 8 points

To effectively prevent rat infestations, Singapore residents should focus on a multi-faceted rat control approach. Start by sealing common entry points like gaps around doors, windows, and pipes with durable materials such as steel wool and caulk. This prevents rats from entering homes. Proper waste management is crucial; ensure garbage and compost are stored in rodent-proof bins and disposed of regularly to avoid attracting rats. Additionally, proper food storage is essential—use airtight containers to store food and promptly clean up crumbs and spills to eliminate food sources for rats.

Maintaining cleanliness with regular cleaning routines, especially in kitchens and storage areas, is vital to prevent infestations as a preventive way to avoid difficult rat control in Singapore. Pay particular attention to areas under appliances and in pantry corners where food debris can accumulate. Overgrown vegetation around homes can serve as nesting sites for rats, so trim bushes and maintain a tidy garden to reduce hiding spots. Also, implement garden maintenance tips like removing fallen fruits and keeping compost bins secure.

Residents should also be vigilant about fixing leaky pipes and eliminating standing water, as rats need water sources to survive (this will also help you fight mosquitoes). Engage professional pest control services if there are signs of a severe infestation. These measures, combined with ongoing vigilance and maintenance, will help keep homes rat-free and ensure a healthier living environment.

Tips for HDB and Condo Residents

For residents of HDB flats and condominiums, securing waste chutes is crucial in preventing rat infestations. Ensuring that waste chutes are properly closed prevents rats from accessing waste and proliferating within the building. Conducting regular inspections of common areas for signs of rats, such as droppings or gnaw marks, is also essential. Routine checks can help detect an infestation early and allow for prompt action to be taken. For more information on rat issues in Singapore, refer to CNA and The Straits Times.

Tips for Landed Properties

Residents of landed properties should focus on outdoor maintenance to keep their premises rat-free. This involves keeping gardens and yards clean and free of debris, such as piles of wood or leaves, which can serve as nesting sites for rats. Additionally, pet food should be stored securely in airtight containers to avoid attracting rats. Ensuring that pet food is not left out overnight can significantly reduce the risk of rat infestations. By following these tips, residents can create a less inviting environment for rats and maintain a healthier living space.

Prevention Strategies for Businesses

Implementing robust rat control in Singapore policies is vital for businesses to prevent rat infestations. Regular pest control checks should be scheduled to ensure early detection and management of any infestations. Educating staff on identifying and reporting signs of rat activity is also crucial. Staff training sessions can empower employees to take proactive measures. Additionally, businesses should adopt proper storage practices by organizing storage areas ensuring all food and materials are stored in rodent-proof containers, and engaging an SFA-compliant pest controller.

Tips for F&B Establishments

Maintaining high cleanliness standards in food preparation and storage areas is essential for food and beverage establishments to prevent rat infestations. According to the SFA’s Good Pest Management Practices, this involves regular cleaning and sanitization of all surfaces to prevent attracting rats. Conducting frequent inspections for rat activity, particularly in storage areas, helps in early detection and effective management. Regular checks ensure that any signs of infestation are promptly addressed, maintaining the hygiene and safety of the establishment. These measures, combined with proper waste management and staff training on pest control, are vital for keeping food establishments free from pests.

Tips for Hotels

Hotels must prioritize maintenance to prevent rat infestations by ensuring all potential entry points are sealed. Regular inspections by the maintenance team can identify and seal gaps around doors, windows, and utility lines. Additionally, guest awareness plays a significant role in preventing infestations. Informing guests about the importance of not leaving food out in their rooms can help reduce the risk of attracting rats. Providing secure storage options for food can further enhance these efforts, ensuring a comfortable and pest-free stay for guests.

DIY Rat Control Methods in Singapore

Common DIY Rat Control Approaches

Rat Traps

  • Types of traps: For capturing rats, 3 popular types of traps are snap traps, electronic traps, and live traps. Snap traps are quick, effective, inexpensive, and reusable, but can be dangerous if not handled properly and may not kill instantly. Electronic traps deliver a lethal shock quickly, are easy to set up and clean, and are generally more humane, but they are more expensive and require batteries or electricity. Live traps allow for the humane capture and release of rats and are reusable, but they need regular monitoring and proper handling to prevent the rats from returning if released nearby.
  • Proper placement and usage: Place traps along walls, in corners, and where you see signs of rat activity. Ensure traps are stable and check them regularly.


  • Types of baits and safe usage: Common baits include peanut butter, dried fruit, and bacon. Use bait stations to keep baits secure and accessible only to rats.
  • Precautions around pets and children: Place baits in locations inaccessible to pets and children, such as under appliances or behind heavy furniture.

Ultrasonic Devices

  • Effectiveness and usage tips: Ultrasonic devices emit sound waves that are unpleasant to rats. Place them in rooms where rats are active, but note that their effectiveness may vary.

Setting Up Traps

  • Placement: Place traps along walls, near entry points, and in areas where you find droppings or gnaw marks. Rats tend to travel along walls, so positioning traps there increases effectiveness.
  • Effective baits to use: Use high-protein foods like peanut butter, cheese, dry fish, or meats to attract rats. Replace bait regularly to keep it fresh and appealing.

Using Baits Safely

Safety Precautions

  • Ensuring baits are inaccessible to non-targets: Use tamper-resistant bait stations to prevent pets and children from accessing the bait. Place stations in secluded areas.
  • Monitoring and replenishing bait stations: Check bait stations frequently to ensure they are stocked and functioning. Replace bait as needed and remove any trapped rats promptly to prevent odor and contamination.
